Gender gaps in labor market outcomes persist in South Asia. An open question is whether supply or demand side constraints play a larger role. We investigate this using matched data from three sources in Lahore, Pakistan: representative samples of jobseekers and employers; administrative data from a job matching platform; and an incentivized binary choice experiment. Employers’ gender restrictions are a larger constraint on women’s job opportunities than supply-side decisions. This demand-side gap in quantity of job opportunities closes as education levels increase and jobs become more “white-collar”.
